SHUTTLE-MACHINE EMBRODERYFRAME.

noemen.,

To all fio/0m 'it may concern:

Be it known that l, HENRY HoonnnU- trenini, a citizen oit the United States, and a resident of lll/est Hoboken, in the county of Hudson and State ot N ew Jersey, have invented a new and Improved Shuttle-Machine lilmbroidery-Frame, et which the tol.- lowiiig is a full, clear, and exact description.

This invention relates to improvements in frames for embroidery machines and to what are called section frames and embroidery trames, and has for an object to provide improved stiL-uctures in which no waste spaces are presented.

Another object of the invention is to provide an improved section trame, designed to be formed with stili bracing1 members at the ends and provided with thin bracing members inte 'mediate the ends, so as to contin ually present a rigid section trame ttor receiving' and holding in proper place the embroiderv trames.

Another object 01"' the invention is to nrovide an improved embroidery frame co-acting with the section frame for holding articles to be embroidered in proper position on the section traine and yet permit of ready removal at any time.

In carrying` ont the objects of the inven tion,the section trames may be made o'li any desired length and connected with the machine, by suitable cleats or bracesso as to be Vlirmly and rigidly heldin place. The section trame is `formed with a plurality ol elainping screws tor receiving the embroidery trames and tor permitting' the embroidery trames to be easily applied and removed. The eml'iroidery iframes are formed with ends inten locking with the clamping' screws of the section trame and with side slots or grooves which accommodate article-clamping bars. These article-clamping bars are pivotally connected with one end oi" the embroidery trame, so as to be hinged or pi'votally moved in and out of the grooves in a'm'dying and ren'iovinn' the article from the trame. These grooves may be made sulliciently largre 'for accominodating the article-holding bars and a resilient clamping n'ieinbeii', or may be made semer-hat tlexible, so as to pinch the article againstthe bar without the use oit a resilient clan'ipingr member.

ri. practical embodiment of the invention is represented in the accompanying drawings forming' a part ot this specification, in which Speceaton of Letters Patent.

Q, on line S-e, same being shown on an enlarged scale; Fig. fl is a sect ion through Fig. 2am line ft-Ll, same being` shown on an enlarged scale; F 5 is a sectional view similar to Fig'. el, but showing' a. moditied form of the invention; Fig', 6 is a perspective view of thc embroidery frame; and hin'. Y is a top plan View of part of the modilied Y.Form oil. section frame.

Referring to the accoinpanyiug drawings by numeral, l iiidicatcs a section :li-anw formed with side angle bars 2 and 3 and end angle bars l. A plurality oi bracing' bars are arranged between the ends ot the iranie7 so as tI stiitlen the frame. Bars el and are eomparativel y thin, so that il it is desirable bars could be arranged at. spaced intervals for preventing any swaying` or bowing ot bars 2 and lli desired trame Il could be used as tor instance in lfisgj. 7, in which heavv end ba -t are utilized lor properly hol ding` the frame rigidly in place. lilhen the heavy end bars elf are used, the intermediate bracing; hars may be clii'i'iinatfr-al. in this 'torni ot section traine, an eniln'oideiy :l'raii'ie must be omitted at each end, while in the preferred form oit section frame shown in Fin". l, the emln'oidery .'lraine will properly lit against the end bars el. Arranied in the ends ot' section Ytrames are notches o, desigg'neiil to aciii'nnmi'alate a retaining; strip 7 which overlaps ai'ljacent section it'ranies and properlv holds the various section Vtrames alined and correctly in position in the i'iiacliinc. This strip 'T may be screwmh bolted or other wise rigidly secured in place without depart ing' trom the spirit ot the invention. i

rirrangrei'l along the section frame are a plin'ality oiI stops 8, preferably in the 'torni et screws, so as to engae the notch, 9 in the respective einlnoidcry Yl'ranics l0. riihe stops S are arranged in bars "2, while in bars 3 are arranged clampiliig screws ll, preferably 'formed with winged tops, so as to be easily oierated. The screws ll are tor-ined with bosses, so as to lit over the end 'l2 of their respective frames 10, while the body of the screw passes through the notch 13. rIhe notches 18 are made comparatively long so that when the trames 10 are applied or removed, the same will permit the proper longitudinal movement ot the frame in order that the notch 9 will clear the stops 8, after which the trames may be moved longitudinally so that notch 9 will slide beneath the head of stops S. The screw 11 then may be tightened so as to clamp the trames properly in place.

rthe trames 10 may be formed of as many parts as cesired without departing from the spirit of the invention, but preferably they are formed with a body having one piece and with the remaining parts connected therewith by rivets, screws or other suitable securing means. The body 14 is formed with ends 12 and 12', in which are arranged notches or slots 13 and S). Notch 9 is cut away at 9, so as to more easily accommodate the head ot stop 8, shown in Fig. 1. In forming the frame 10, the end members 12 and 12 are connected by longitudinal bars 15 and 1G. substantially U-shaped in cross section, whereby grooves or slots 17 and 18 are provided. These grooves or slots are designed to accommodate clamping arms 19 and 20. Around these clamping arms are arranged rubber gripping means 21, as shown t'or instance in Fig. e. rlhe rubber tube 21 is preferably somewhat compressed so as to properly grip the work 22 and hold the same stretched tightacross the trame trom bar 15 to bar 1G as shown in Fig. 2. The needles ot the machine may vork freely in space between bar 15 and bar 16. It it is desired to wort; a design as shown in Fig. 2, the article 22 is arranged as shown in Fig. 2, but it it should be desired to work a design with its widest, part extending in a direction at right angles to that shown in Fig. the article 22 is turned substantially 9Go and the needles will then properly act t'or working the design. rhe arms 19 and 2O are pivotally connected at. 23 and 24 to a rigidly secured cross brace 25, though it desired. they could be secured directly to end l2. End 12 carries a cross bar 2G on which is pivotally mounted hook members 27 and 2S, designed to hook over the ends ot' arms 19 and 20. Arranged at end 12 oit each of the trames 10, is a clamp 29, termed with a body 30, having depending ears 81 and a biting nose 32. The biting nose 32 is adapt-- ed to bite or pinch article 22 against. end 12 tor assisting' in holding the article properly in place and in the proper stretched condition. The ears 31 have passing therethrough a shaft 38 mounted in ears 34, preferably termed integral with end 12. A spring surrounds shaft 33 and has one end pressing against end 12 and the other against body 80, so as to normally press nose 32 against end 12.

1n the construction of the section trame 1 and the detailed construction of the em broidery trames 10, it will be noted that the embroidery trames may be readily applied and removed Whenever desired. For instance, any particular embroidery frame may be removed and again applied without in any way molesting or working upon any ot the remaining trames.

Having thus described my invention, I claim as new and desire to secure by Letters Batentzd 1. ln an embroidery trame ot' t ie class described, the combination with a section trame having clamping pins, of a trame toi-med with a body having end members and grooved connecting members, said end members being formed with notches adapted to straddle said pins, whereby said body is removably mounted on said section trame, and pivotally mounted clamping bars coacting with said grooved connecting members tor clamping an article to said body.

2. ln an embroidery trame of the class described. the combination with a section trame having a stationary pin on one edge formed with a head, and an adjustable pin on the opgosite edge :toi-med with a head, of a trame t'or receiving an article, said trame comprising a body formed with end members and connecting grooved bars, said end members having notches therein, one ot said notches being deeper than the other, whereby the deeper notch is caused to slide over one ot said pins so that the opposite end of the body may be substantially Hush with the pin on the opposite side of the section trame, said section trame being adapted to be moved over said last mentioned pin so that the end ot the body will straddle said last mentioned pin, hinged bars adapted to tit into said grooved members, and hooked members tor holding said hinged bars in place.

1n testimony whereof i have signed my name to this speciication in the presence ot two subscribing witnesses.
